I have been using ADO as a connection tool for access 97. <br>All was good. <br>I recently changed to access 2000. <br>suddenly things went bad. <br>I could not connect using DAO - I got an error message telling me the file format is unrecodnized after converting the mdb file to access 2000 format. <br>Has the world gone mad??? <br>Is there somthing I'm missing ? <br>Thanks. <br>Dan.<br>
